Question

using RhinoMocks I would like to raise a event, where the event handler signature looks like:
MyEventHandler(int a value, ref bool handled) {..}

If I use:
myMock.Raise(x => x.MyEventHandler += null, aValue, handled);

I get the following Error message:
System.InvalidOperationException: Parameter #2 is System.Boolean but should be System.Boolean&

I tried it with:
myMock.Raise(x => x.MyEventHandler += null, aValue, ref Arg<bool>.Ref(Is.Anything(), handled).Dummy);
but that doesn’t even compile…

What Is the right way to raise this event?

Take a look on following example

[Test]
public void RaiseEvent()
{
    var mock = MockRepository.GenerateMock<IEventsRaiser>();
    mock.GetEventRaiser(x => x.MyEvent += null).Raise(1, Arg<bool>.Ref(new Anything(), true).Dummy);
}

public delegate void MyEventHandler(int a, ref bool handled);

public interface IEventsRaiser
{
    event MyEventHandler MyEvent;
}
